I tried many many different hubs, found the Belkin range to work without any hassles (recommended by another IIS member). Been using it with any and every USB peripheral for my imaging rig for over two years. They also offer a 7-port version too.

I personally avoid having anything on my scope to reduce the stress on the mount and have opted to use a single loom to feed all my USB cables from the scope to the hub/computer. By far the best investment ever made, not having to fumble around and connect 6-7 cables at every session!
